#1 is correct..
start by cross multiplying
7(x-3) = 7x - 21 4*21 = 84 so 7x - 21 = 84 I presume you can take it from there
So B, X=15?
to convert any number to a percent, just multiply by 100
3.1*100 = ?
what is 3.1 times 100?
@Ms-Brains Please stop posting questions with no work shown. It is not appropriate for you to get others to do your homework or exams for you. Let's see what YOU can do.
Okay @tkhunny I already did the work, and I was just making sure they were correct. Sorry! I didn't know I can't do that. ;-;
3.1 * 100 = 310.0
good, so which answer choice do you think it is?
You did not address my concern. All cheaters say, "I already did the work." The ONLY way for you to differentiate yourself from cheaters is to SHOW your work, not merely claim that you did it. Show YOUR work.
Okay, give me a second to copy my work from paper to the the drawing pad. Lol, Dude I'm not afraid to show my work, it just seems easier like this. But yeah, I'm sorry. And I will post the work from now on. :)
@tkhunny That good?
yeah that looks good to me
(there's a simpler way to do it, though. 24 is 3 times 8, so the missing number must be 3 times 7)
yeah to show your work I would just write (0.24)*75
or, now that I realize it, (0.24)*75 = 0.75*24 = (3/4)*24 = 18
yeah 0.36x = 180
hm not quite
keep the proportion consistent either do miles/gallons = miles/gallons or gallons/miles = gallons/miles
(so, like, don't do something like gallons/miles = miles/gallons because that won't work)
Oh, So If I do 115/5 = 18/x It wouldn't be correct?
right, because on the left side you have miles/gallons and on the right side you have gallons/miles
is it x/115 = 5/18?
hmm not quite
you would need to switch x and 115 for that to work
You tell me if it's good. If it's YOUR work, then it's great. Not so much, otherwise.
Hmm? That would mean it is 5/115 = 18/x But ^ that is the same as 5/115 = x/18. Just the back is switched and that doesn't make sense ;-;
Yes, it's my work. Omg, I said I'm sorry. I didn't mean to violate any policy of anything. ;-; @tkhunny
nope, not quite 5/115 = 18/x and 5/115 = x/18 are not the same proportion
if you want to keep the two sides equal, you have to switch both, not just one
5/115 = 18/x is the correct solution because it puts gallons/miles = gallons/miles
You and Vocaloid seem to be getting along very well. If you posted questions on separate threads, as is customarily recommended, you could give Vocaloid more medals for all the good work. :-)
Oh...okay. I get it now! so back to the question.. it's C, right?
ahaha I don't really care about medals, I just do this for fun :P
nope not C, think carefully
D, 0-0 I give up if it's not this Dx
yeah it's D
Yay me! Let me post a new thread for you to get more medals :) Give me a second
